To clarify, it's completely up to the user as to how to use/project identities.

For example, a single human might choose to at least have one professional identity and one hobby identity. Or heaven forbid a trolling identity.
Heck, they could choose to start a new identity for each season of the year.

As it stands technological limitations require an identity to be split between different services. It sure would be nice if those barriers could come down, leaving it up to the user to decide how to represent each identity they wish to be.
